#betta question

how much, and how often, do you feed your fish? i thought i was giving my little guy a good meal with either a single pellet/pinch of flakes/couple bloodworms once per day, mostly because of how awful overfeeding was made out to be by basically everything i saw online. however, now i'm starting to worry that i'm not giving him quite the nutrients he needs, as he does look pretty skinny in comparison to some other fish i've seen. any advice or personal experience would be greatly appreciated-- please help a lil fish pal out!

So back in the day (aka over the summer) when I actually did my fishless cycling with ammonia, I got nitrate readings. However, since I've had fish in the tanks I've never gotten a nitrate reading (using the liquid API test kit). Am I doing something wrong? I've been dosing stability with each weekly water change because I'm worried about my cycle, but still nothing. No ammonia, no nitrites, and no nitrates. Is it possible that it is cycled, and the bioload is just low enough that the few plants I have take up all the nitrates? Or is it actually not cycled?

so i just got home and the water here is drinkable but like. has a lot of chemicals in it to make it so. Would conditioning it be enough or do i have to actually buy purified water for my fish? 

Hey guys! Has anyone else ever seen this before? Our new Betta (who seems to be in perfect health otherwise) seems to have one of his back fin rays not completely encased in his tail. What would have caused this? Is it going to affect his life in any way? For now it seems to be ok. (Fin ray is supposed to be in the shiny blue/green section of his back fin.)

My betta always seems to be glass surfing. He has many decorations and a hiding place and driftwood tannins and plants to hide in, yet he never seems to be anywhere but along the glass, either in the front begging for food or in the back playing behind the filter and then under the water current and back again. He does not seem to be stressed in any way, parameters are fine, he eats twice a day.. am I doing something wrong? I tried rearranging his tank twice and he never makes bubble nests or swims through/around his decorations. At least when I'm not in the room. Does anyone else have bettas like this? Any tips to get him to explore his environment a little more?

I’ve moved Jasper into a hospital tank. He started swimming weird last night and today he’s been resting on things and not moving around much. I tried to feed him a thawed pea but he isn’t eating. Does anyone have any other ideas to help him? I’m scared he might be dying.

Has anyone had their betta fish naturally lose color? Jasper's turned a metallic grey-blue color in the past month. He's acting normally, swimming and eating okay and his water is testing perfect. Does anyone have an idea of why this happened?
